Agenda for the 93rd Mahara developer meeting on Tuesday, 24 January 2023 at 23:00 UTC

We will meet online using Big Blue Button (A Catalyst staff member will initiate the call).

Our #Mahara channel on Matrix will be our backup in case there are problems with the web conferencing tool and we'll need to chat to resolve it. You can connect to our Matrix channel also using the #mahara channel on Freenode IRC.

  • Chair: Doris Tam
  • Minute taker: Gold

Chair and minute taker duties explained

Agenda

Items from previous meetings

  • Change to makefile to add some basic security checks
  • Update coding and code review guidelines to add words around security
  • PHP 8.1 progress
  • Idea to progress towards PHP 8.1: Introduce a project-wide linter
    • What we currently have: make minaccept
      1. Written in 2010 at the time of PHP 5.3 standards (12 years ago, which matched that standards at the time of it was written)
      2. Unmanaged and difficult to update and manage as it's hard-coded, covering a small subset of rules
    • How does a linting tool help us?
      1. Less time spent on syntax, more on implementing and pushing solutions (towards PHP 8 compliance).
      2. Easily to change, update, and adapt the rules within the project as we need and in our speed.
      3. Eventually, CI/CD can warn us of issues of new code we push the code before merging, i.e. on GitLab
      4. With a standardised syntax, the core team can more easily work with community patches and get them in faster.
    • What is a linter and formatter?
      • A linter is a static analysis tool that can show us area of bad coding practice.
      • A static analysis tool to find weak spots in the code, highlighting issues
      • where rules are configurable
      • We can change the strictness, warnings vs. errors.
      • Formatters provide syntax checking and updates code
    • How does it help other teams at Catalyst?
      • The frontend team use Prettier formatter – a set of rules to follow
      • Fix once, get the benefits going forwards with minimal changes
      • By using Prettier for JavaScript, they can adjust the rules in a prettier.rc/.json for each project.
